Before you begin using ION-Sei, we recommend you charge it for at least 10 hours.
After it runs out of battery, we suggest you charge it for at least 10 hours.
Once it's fully charged, ION-Sei will last for 3 weeks when used about twice a day, 2 minutes each.
When UV light reaches the titanium dioxide bar, photocatalysis occurs and generates negative ions that help to clean your teeth more effectively.
The dentist recommends brushing your teeth for 2 minutes at least twice a day.
Please view the user guide for additional information.
We recommend changing the toothbrush head once every 3 months, but if you brush your teeth 3 times per day, we recommend changing it every 2 months.
We do not recommend 2 people share 1 brush head for sanitary reasons.
While you should not submerge your ION-Sei in any water, it is safe to use in the shower or splash the toothbrush with water for cleaning purposes.
To remove the handle, firmly hold the brush head and pull it upwards away from the handle. To add a new brush head, slide your replacement brush head down on to the handle.
Our brush heads only work with ION-Sei.
ION-Sei was designed in Japan and manufactured in our company-owned factories in China.
Yes. However, if you’re traveling for longer than 2 weeks, we recommend you bring the toothbrush charging base and USB cord with you.
We advise you to check with your child’s dentists before they use ION-Sei. In most cases, we don't recommend children under 10 years old to use an electric toothbrush as their gum is still growing and could get damaged.
In the first few days of using your electric toothbrush, your gum may bleed slightly as your teeth may not be used to the strokes. If bleeding persists after 2 weeks, please consult your dental hygienist.
Yes, ION-Sei is specifically designed for people with sensitive teeth and gums. Our motor and strokes are extremely gentle and quiet since we depend on the power of ions to do the cleaning. We recommend you to use "sensitive mode" if you have sensitive teeth and gums.
The ION-Sei toothbrush is not designed to be used near any medical electronic equipment or home therapeutic apparatus (i.e. pacemaker or other implants fitted) for its weak currents can cause interference or malfunction of the medical devices and lead to accidents or health issues.
